A humpback whale caught in fishing ropes off the coast of Cornwall in south-west England has been saved thanks to the efforts of local rescuers.

According to Marine Industry News, the whale known locally as “Ivy” became entangled in Mounts Bay on Easter Sunday (31 March) and was soon spotted in distress by both fishing crews and a wildlife-watching tour.

Conditions at sea were choppy at the time, meaning these onlookers could not intervene.

But in the afternoon Penlee RNLI’s volunteer lifeboat crew came to the rescue, cutting the whale free from their inshore lifeboat.

Hannah Wilson, co-owner of tour group Marine Discovery Penzance said: “It’s incredible what the guy at the helm achieved because it was properly rough.”

A Bermudan whale researcher has confirmed that a humpback photographed in Bermudan waters is “Hookie”, which has been spotted in Irish waters.

As The Royal Gazette reports, Andrew Stevenson of Whales Bermuda said this was not only the first match of a Bermuda whale to Ireland.

The Bermudan English language publication also quotes him as stating this is “also the first match between north America and the British isles”. [sic]

Humpback whales can be identified by the pattern on their flukes — the double lobes of the animal’s tails.

Whales Bermuda set up a programme in 2007 to document whales on their migratory route past the island to the Caribbean.

“Hookie”, a male humpback, was recorded in Irish waters back in January and February 2010, and was photographed off Bermuda in 2015 by Whales Bermuda crew member Camilla Stringer.

He was sighted in June and July 2013 off the French territory islands of St Pierre et Miquelon, just off Newfoundland, Canada, and visited Trinity in Newfoundland “numerous times in 2018 and 2021”, Mr Stevenson said.

Analysis of the signature pattern has now revealed that the Bermuda whale, No 1450, was the same animal as the Ireland sighting of Hookie, Stevenson has said.

He said it is believed that Irish and British Isles humpback whales migrate to Cabo Verde in the eastern north Atlantic.

“But Hookie shows us that the more we know, the more we don't know.”

He thanked Ms Stringer for the original Bermuda identification, along with Padraig Whooley of the Irish Whale and Dolphin Group, touring company Sea of Whales Adventures based in Newfoundland, and Roger Etcheberry and Joel Detcheverry in St Pierre et Miquelon.

The Irish Whale and Dolphin Group’s (IWDG) documentary on the trail of the humpback whale is to be screened in Kilnaboy, Co Clare today (Thur Apr 6).

The documentary “Ireland to Iceland – On The Trail Of The Humpback Whale” will be shown at the X-PO in Kilnaboy at 8 pm.

As The Clare Herald reports, the IWDG embarked on the unique research expedition in 2018.

“During the month-long navigation of Iceland’s coast, a revolving crew of volunteers visited remote coastal communities,” the newspaper says.

“They documented humpback whales in abundance, as well as recording many other species, including Blue whales and the critically endangered White-beaked dolphin,” it says.

The documentary of the voyage was shot by award-winning filmmaker Tony Whelan.

The screening will be followed by a question and answer session with Whelan, the IWDG chief science officer, Dr Simon Berrow, and expedition team members.

Admission is free, and donations to the IWDG are welcome.

A humpback whale seen in Irish waters in January of 2010 and not reported again for thirteen years has been spotted off Newfoundland.

Sighted on January 17, 2010, inshore off Hook Head, County Waterford, by Irish Whale and Dolphin Group members, a biopsy obtained under a National Parks and Wildlife Service licence confirmed it as a young sub-adult male and a new humpback in Irish waters.  It was added to the IWDG’s Irish Humpback Whale Catalogue as #HBIRL11.

“As with all humpbacks photographed in Irish waters, images of it were shared with IWDG partners ‘Allied Whale’ at the College of the Atlantic, Bar Harbor, Maine, USA, who manages the North Atlantic Humpback Whale Catalogue and have a database of 11,000+ individual humpbacks,” according to the IWDG.

It had remained adjacent to Hook Head Peninsula until February 28, 2010, and was regularly observed feeding on sprat and herring, often in the same area as fin whales and short-beaked common dolphins.

For the past 13 years, ‘Hooky’ as he was colloquially dubbed has not been recorded in Irish waters,  but Allied Whale has now told IWDG it was seen off Newfoundland in 2018 and 2021.

“This is an important development, the first re-sighting between Ireland/British Isles and the western North Atlantic feeding grounds,” said Padraig Whooley, IWDG Sightings Officer. “The fact that this whale has been recorded in two known feeding areas, Newfoundland (Summer) and Irish South coast (Winter), is noteworthy.”

A new individual Humpback Whale, nicknamed ‘Orion’, has been sighted for the first time in Irish waters, approximately 60 kilometres north-northwest of Malin Head, Co Donegal.

The humpback whale was sighted onboard the Marine Institute’s RV Celtic Explorer as part of the annual Western European Shelf Pelagic Acoustic (WESPAS) survey. The humpback whale was sighted at 9.30 am on Friday 9th July 2021 by Dr Justin Judge, a Marine Mammal Observer who was on board the RV Celtic Explorer on behalf of the Irish Whale and Dolphin Group (IWDG). The IWDG confirmed the humpback whale is a new individual, previously unrecorded in Irish waters in the IWDG catalogue and has been given the Catalogue Number HBIRL111.

“This is a dream sighting for a Marine Mammal Observer,” Dr Justin Judge said. “The individual humpback whale ‘Orion’ has been named after the Greek mythological hunter, since the whale was moving with the fish stocks for food. It is also my son’s middle name so fitting on both fronts. There was a lot of feeding action from a multitude of cetacean species that day, including Bottlenose, Common, Risso’s and White-Sided dolphins, grey seals and Minke whales.”

Humpback whales grow up to 14 to 17 metres long, and are predominantly black in colour with long white flippers and often white patches on the underside (ventral surface). When a humpback whale raises its tail or fluke, it provides an opportunity to photograph its underside. The pattern on the underside is unique to that individual whale, and these photographs are used to identify it. To date, the Irish Whale and Dolphin Group has documented 112 individual humpback whales in Irish waters since 1999, many of which are recorded year after year.

“Observing any apex predator in its natural environment is exciting but a new humpback whale for Irish waters, this is special,” WESPAS Survey scientist, Ciaran O’Donnell of the Marine Institute said. “Irish waters support a diverse range of marine life, and our annual acoustic survey programme not only monitors the health of our pelagic fish stocks, but also provides data to researchers on the overall health of the wider ecosystem. Observing and understanding our ocean, is essential for protecting and managing our marine ecosystems for the future.”

The Marine Institute’s WESPAS survey is carried out annually, and surveys shelf seas from France northwards to Scotland, and west of Ireland. WESPAS is the largest single vessel survey of its kind in the Northeast Atlantic, covering upwards of 60,000 nmi2 (nautical miles) every summer. The survey is funded through the European Maritime Fisheries and Aquaculture Fund under the Data Collection Programme which is run by the Marine Institute. Scientists collect acoustic and biological data on herring, boarfish and horse mackerel, which is used to provide an independent measure of these fish stocks in Irish waters. Scientists also monitor the physical and chemical properties of the seawater, plankton, sea birds and marine mammals during this survey.

Humpback whales are a migratory species. They can be seen in Irish waters throughout the year, but the most frequent sightings occur in spring through to early winter when they visit seasonal feeding grounds. Irish waters are an ideal feeding area for humpback whales, as it is midway on their migration across the Atlantic between Western Africa and Northern Scandinavia. Images of individual humpback whales can be used to track their local short range movements as well as their international movements along migration routes and ultimately their breeding ground.

#MarineWildlife - Galway residents have a great opportunity to see a wild dolphin close to the city centre with the return of regular visitor to the Nimmo’s Pier area this week.

Nicknamed Nimmo, the solitary bottlenose dolphin was first sighted in the city in April 2015 and since then has become an annual fixture, appearing and staying longer each time.

The Irish Whale and Dolphin Group (IWDG) suggests this is a sign that the area around Galway city is now a “more important core feeding habitat for Nimmo”.

In other news, the IWDG’s research vessel Celtic Mist will embark on a series of week-long surveys this summer in search of humpback whales.

IWDG members are invited to join any of the nine legs, the first of which sets sail from 9-15 June (weather permitting) between Cork and Dingle/Fenit.

For details on how to book a place on any of these voyages and for further information, contact [email protected].

#MarineWildlife - A small Norwegian community in the Arctic Circle recently had a whale of a problem with their internet connection - literally.

As New Scientist reports, a subsea internet cable in the Kaldfjorden north of Tromsø which should have been 170m below the surface broke loose from the fjord bed and entangled one of its many humpback whale visitors for more than a day.

Believing at first that the marine giant was caught in fishing gear, rescuers discovered after finally freeing the whale that it had been caught in a data cable - hence the affectionate nickname ‘Hacker’.

#MarineWildlife - Whale sightings are on the increase in the South East this week as the season tapers off, according to the Irish Whale and Dolphin Group (IWDG).

"As large whales don't keep to our calendar year, this annual south east flurry of large whale sightings represents the tail-end our our large whale season," says the IWDG's sightings officer Pádraig Whooley.

"And what a season it has been, especially for the humpback whale, which have enjoyed a record year both in terms of frequency of sightings since they first appeared in early May off the Slea Head Peninsula."

The latest spots were made both on land – by Andrew Malcolm and Ann Trimble from Ardmore Co in Waterford at the weekend – and on a whale-watching trip with Martin Colfer's South Coast Charter Angling, recording a humpback whale and more than five fin whales between them.

And there might still be time to head down to the Sunny South East to catch a glimpse of these ocean giants before they depart for the spring.

Ireland's Offshore Renewable Energy

Because of Ireland's location at the Atlantic edge of the EU, it has more offshore energy potential than most other countries in Europe. The conditions are suitable for the development of the full range of current offshore renewable energy technologies.

Offshore Renewable Energy FAQs

Offshore renewable energy draws on the natural energy provided by wind, wave and tide to convert it into electricity for industry and domestic consumption.

Offshore wind is the most advanced technology, using fixed wind turbines in coastal areas, while floating wind is a developing technology more suited to deeper water. In 2018, offshore wind provided a tiny fraction of global electricity supply, but it is set to expand strongly in the coming decades into a USD 1 trillion business, according to the International Energy Agency (IEA). It says that turbines are growing in size and in power capacity, which in turn is "delivering major performance and cost improvements for offshore wind farms".

The global offshore wind market grew nearly 30% per year between 2010 and 2018, according to the IEA, due to rapid technology improvements, It calculated that about 150 new offshore wind projects are in active development around the world. Europe in particular has fostered the technology's development, led by Britain, Germany and Denmark, but China added more capacity than any other country in 2018.

A report for the Irish Wind Energy Assocation (IWEA) by the Carbon Trust – a British government-backed limited company established to accelerate Britain's move to a low carbon economy - says there are currently 14 fixed-bottom wind energy projects, four floating wind projects and one project that has yet to choose a technology at some stage of development in Irish waters. Some of these projects are aiming to build before 2030 to contribute to the 5GW target set by the Irish government, and others are expected to build after 2030. These projects have to secure planning permission, obtain a grid connection and also be successful in a competitive auction in the Renewable Electricity Support Scheme (RESS).

The electricity generated by each turbine is collected by an offshore electricity substation located within the wind farm. Seabed cables connect the offshore substation to an onshore substation on the coast. These cables transport the electricity to land from where it will be used to power homes, farms and businesses around Ireland. The offshore developer works with EirGrid, which operates the national grid, to identify how best to do this and where exactly on the grid the project should connect.

The new Marine Planning and Development Management Bill will create a new streamlined system for planning permission for activity or infrastructure in Irish waters or on the seabed, including offshore wind farms. It is due to be published before the end of 2020 and enacted in 2021.

There are a number of companies aiming to develop offshore wind energy off the Irish coast and some of the larger ones would be ESB, SSE Renewables, Energia, Statkraft and RWE.

There are a number of companies aiming to develop offshore wind energy off the Irish coast and some of the larger ones would be ESB, SSE Renewables, Energia, Statkraft and RWE. Is there scope for community involvement in offshore wind? The IWEA says that from the early stages of a project, the wind farm developer "should be engaging with the local community to inform them about the project, answer their questions and listen to their concerns". It says this provides the community with "the opportunity to work with the developer to help shape the final layout and design of the project". Listening to fishing industry concerns, and how fishermen may be affected by survey works, construction and eventual operation of a project is "of particular concern to developers", the IWEA says. It says there will also be a community benefit fund put in place for each project. It says the final details of this will be addressed in the design of the RESS (see below) for offshore wind but it has the potential to be "tens of millions of euro over the 15 years of the RESS contract". The Government is also considering the possibility that communities will be enabled to invest in offshore wind farms though there is "no clarity yet on how this would work", the IWEA says.

Based on current plans, it would amount to around 12 GW of offshore wind energy. However, the IWEA points out that is unlikely that all of the projects planned will be completed. The industry says there is even more significant potential for floating offshore wind off Ireland's west coast and the Programme for Government contains a commitment to develop a long-term plan for at least 30 GW of floating offshore wind in our deeper waters.

There are many different models of turbines. The larger a turbine, the more efficient it is in producing electricity at a good price. In choosing a turbine model the developer will be conscious of this ,but also has to be aware the impact of the turbine on the environment, marine life, biodiversity and visual impact. As a broad rule an offshore wind turbine will have a tip-height of between 165m and 215m tall. However, turbine technology is evolving at a rapid rate with larger more efficient turbines anticipated on the market in the coming years.

 

The Renewable Electricity Support Scheme is designed to support the development of renewable energy projects in Ireland. Under the scheme wind farms and solar farms compete against each other in an auction with the projects which offer power at the lowest price awarded contracts. These contracts provide them with a guaranteed price for their power for 15 years. If they obtain a better price for their electricity on the wholesale market they must return the difference to the consumer.

Yes. The first auction for offshore renewable energy projects is expected to take place in late 2021.

Cost is one difference, and technology is another. Floating wind farm technology is relatively new, but allows use of deeper water. Ireland's 50-metre contour line is the limit for traditional bottom-fixed wind farms, and it is also very close to population centres, which makes visibility of large turbines an issue - hence the attraction of floating structures Do offshore wind farms pose a navigational hazard to shipping? Inshore fishermen do have valid concerns. One of the first steps in identifying a site as a potential location for an offshore wind farm is to identify and assess the level of existing marine activity in the area and this particularly includes shipping. The National Marine Planning Framework aims to create, for the first time, a plan to balance the various kinds of offshore activity with the protection of the Irish marine environment. This is expected to be published before the end of 2020, and will set out clearly where is suitable for offshore renewable energy development and where it is not - due, for example, to shipping movements and safe navigation.

YEnvironmental organisations are concerned about the impact of turbines on bird populations, particularly migrating birds. A Danish scientific study published in 2019 found evidence that larger birds were tending to avoid turbine blades, but said it didn't have sufficient evidence for smaller birds – and cautioned that the cumulative effect of farms could still have an impact on bird movements. A full environmental impact assessment has to be carried out before a developer can apply for planning permission to develop an offshore wind farm. This would include desk-based studies as well as extensive surveys of the population and movements of birds and marine mammals, as well as fish and seabed habitats. If a potential environmental impact is identified the developer must, as part of the planning application, show how the project will be designed in such a way as to avoid the impact or to mitigate against it.

A typical 500 MW offshore wind farm would require an operations and maintenance base which would be on the nearby coast. Such a project would generally create between 80-100 fulltime jobs, according to the IWEA. There would also be a substantial increase to in-direct employment and associated socio-economic benefit to the surrounding area where the operation and maintenance hub is located.

The recent Carbon Trust report for the IWEA, entitled Harnessing our potential, identified significant skills shortages for offshore wind in Ireland across the areas of engineering financial services and logistics. The IWEA says that as Ireland is a relatively new entrant to the offshore wind market, there are "opportunities to develop and implement strategies to address the skills shortages for delivering offshore wind and for Ireland to be a net exporter of human capital and skills to the highly competitive global offshore wind supply chain". Offshore wind requires a diverse workforce with jobs in both transferable (for example from the oil and gas sector) and specialist disciplines across apprenticeships and higher education. IWEA have a training network called the Green Tech Skillnet that facilitates training and networking opportunities in the renewable energy sector.

It is expected that developing the 3.5 GW of offshore wind energy identified in the Government's Climate Action Plan would create around 2,500 jobs in construction and development and around 700 permanent operations and maintenance jobs. The Programme for Government published in 2020 has an enhanced target of 5 GW of offshore wind which would create even more employment. The industry says that in the initial stages, the development of offshore wind energy would create employment in conducting environmental surveys, community engagement and development applications for planning. As a site moves to construction, people with backgrounds in various types of engineering, marine construction and marine transport would be recruited. Once the site is up and running , a project requires a team of turbine technicians, engineers and administrators to ensure the wind farm is fully and properly maintained, as well as crew for the crew transfer vessels transporting workers from shore to the turbines.

The IEA says that today's offshore wind market "doesn't even come close to tapping the full potential – with high-quality resources available in most major markets". It estimates that offshore wind has the potential to generate more than 420 000 Terawatt hours per year (TWh/yr) worldwide – as in more than 18 times the current global electricity demand. One Terawatt is 114 megawatts, and to put it in context, Scotland it has a population a little over 5 million and requires 25 TWh/yr of electrical energy.

Not as advanced as wind, with anchoring a big challenge – given that the most effective wave energy has to be in the most energetic locations, such as the Irish west coast. Britain, Ireland and Portugal are regarded as most advanced in developing wave energy technology. The prize is significant, the industry says, as there are forecasts that varying between 4000TWh/yr to 29500TWh/yr. Europe consumes around 3000TWh/year.

The industry has two main umbrella organisations – the Irish Wind Energy Association, which represents both onshore and offshore wind, and the Marine Renewables Industry Association, which focuses on all types of renewable in the marine environment.
